The main goal of this study is to analyze the phase synchrony of balloon inflation with cardiac frequency using a robotic device and assess its dilatation performance compared to the standard. A pressure sensor was hydraulically connected to the ventricular chamber of a ViVitro Pulse Duplicator (ViVitro Labs, Inc. Victoria, BC, Canada). The ViVitest software enables the analysis of the flow rate and pressures of the aortic and ventricular chambers and the estimation of the effective orifice area. Our method shows better dilatation performance, as evidenced by notable improvements in pressure gradient and aortic valve opening area.
